Genetic Variation in Meiosis Concept, Function & Significance

WebGenetic variation is also introduced by random fertilization of the gametes produced by meiosis. Any of the genetically unique sperm generated by a male may fertilize the genetically unique egg produced by a female. During metaphase I, the homologous pairs of chromosomes are aligned along the metaphase plate. WebWithout genetic variation, some key mechanisms of evolutionary change like natural selection and genetic drift cannot operate. There are three primary sources of new genetic variation: Mutations are changes in the information contained in genetic material. (For most of life, this means a change in the sequence of DNA.) A single mutation can have a

It is responsible for reducing the ploidy level of gametes from diploid to haploid. One germ cell goes through the meiosis cycle twice to form four haploid gametes. Two nuclear divisions are followed by- two subsequent cellular divisions in this cycle.
